(Vers. 7, 8.) But on the contrary, when they saw that I had been entrusted with the gospel for the uncircumcised, just as Peter had been entrusted with the gospel for the circumcised (for he who worked through Peter for his apostolic ministry to the circumcised worked also through me for mine to the Gentiles), and when James and Cephas and John, who seemed to be pillars, perceived the grace that was given to me, they gave the right hand of fellowship to Barnabas and me, that we should go to the Gentiles and they to the circumcised. Ὑπέρβατον est, et multis quae in medio sunt interjecta sublatis, sic breviter legi potest: Mihi enim qui videbantur esse nihil contulerunt: sed econtra dexteras dederunt mihi et Barnabae, societatis. Aut certe ille absque jactatione sui, occultus est sensus: Mihi qui videbantur esse aliquid, nihil contulerunt; sed econtra a me eis collatum est, dum fiunt in Evangelii gratia firmiores. Totum autem quod dicit, hoc est: unus atque idem mihi Evangelium praeputii, et Petro circumcisionis credidit. He sent me to the Gentiles, and he appointed him in Judea. Neither could the Gentiles, who were no longer young and could not benefit from the pain of circumcision, abstain from the foods they had always been accustomed to and that God had created for them to use; nor could those who believed and were circumcised from the Jews, and who, by custom, thought they had more than the other Gentiles, easily despise the things in which they boasted. Therefore, by the providence of God, one apostle was given to the circumcised, who seemed to acquiesce to the shadows of the Law, while another was given to those who were uncircumcised, who did not consider the grace of the Gospel to be slavery, but rather free faith. Lest any impediment to faith arise under any occasion: and because of circumcision or uncircumcision, one would not believe in Christ. And we do not say this because Peter, who himself also testified that no man is common in the Acts of the Apostles (Acts 10), and is taught in that vessel, which he saw sent from heaven with four corners, that it makes no difference whether someone is a Jew or a Gentile, as if he had forgotten the things that came before, concerning the grace of the Gospel, he considered the Law to be observed. But rather, in order to also pretend to keep the Law himself, gradually leading the Jews away from their ancient way of life. For they could not suddenly and contemptuously cast aside so much labor of observance, and the most careful conduct of their former life, as if it were mere refuse and loss. Hence we may clearly understand why Paul and Barnabas, who were in society with Peter, James, and John, received the right hand of fellowship from them. It was not to prevent the gospel of Christ being thought different among those who hitherto observed various rites, or who held diverse opinions, but to establish a common bond both between those who were circumcised and those who were not. Paul wisely maintained this, when he said, 'For He that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles; and recognizing the favor conferred upon Peter, he thus explains it, that it might be understood how, in receiving circumcision, he did it in part, in order that he might profit those who had believed in him among the Jews, and keep them in the faith and gospel of Christ.' He also understands that if that person were to act without fault and observe the time when it is not allowed, so as not to lose those entrusted to him, he would have to do more for the truth of the Gospel, namely, what was entrusted to him in secret, so that the nations, discouraged by the burden and difficulty of the Law, would not turn away from the faith and belief in Christ. A hidden question arises here: So what? If Peter were to find [people] from the Gentiles, would he not lead them to the faith? But if Paul had found any from the circumcision, did he not invite them to the baptism of Christ? This is resolved in the following way: that we say that it was commanded for each group, the Jews and the Gentiles, that those who defended the Law would have someone to follow, and those who preferred grace over the Law would have a teacher and guide. But in general, their purpose was to gather the Church of Christ from all the nations. For we read that the Gentile Cornelius was baptized by the holy Peter, and that Paul often preached Christ in the synagogues of the Jews. Peter, John, and James, who seemed to be pillars (Acts X, XIII, XVII). Three times before we have read about the Apostles, but after them were the others who seemed to be something. They made no difference to me, those who seemed important. So I was anxious to know what this meant, those who seemed important, but now he has relieved me of all doubts by adding, who seemed to be pillars. Therefore, the pillars of the Church are the apostles, especially Peter, James, and John, among whom two of them deserve to ascend the mountain with the Lord, one of whom introduces the Savior speaking in the Apocalypse: 'To him who overcomes, I will make him a pillar in the temple of my God' (Rev. 3:12), teaching all believing ones who overcome the adversary that they can become pillars of the Church. Writing to Timothy, Paul says: 'So that you may know how one ought to behave in the household of God, which is the Church of the living God, the pillar and support of the truth' (1 Tim. 3:15). And we are instructed by him and the other apostles, all the believers, and even the Church itself is also called the pillar in the Scriptures. And there is no difference whether it is said about the body or the members, since the body is divided into members and the members are the body. Therefore, Peter, James, and John, who seemed to be pillars, gave the right hand of fellowship to Paul and Barnabas; but Titus, who was with them, did not receive the right hand. For he had not yet reached such a measure, that the merchandises of Christ could be believed to him in equal measure with the elders, and hold the same place of negotiation that Barnabas held, and Paul.
With regard to those (the Marcionites) who allege that Paul alone knew the truth, and that to him the mystery was manifested by revelation, let Paul himself convict them, when he says, that one and the same God wrought in Peter for the apostolate of the circumcision, and in himself for the Gentiles.
Ver. 8. "For He that wrought for Peter unto the Apostleship of the Circumcision wrought for me also unto the Gentiles."
He calls the Gentiles the Uncircumcision and the Jews the Circumcision, and declares his own rank to be equal to that of the Apostles; and, by comparing himself with their Leader not with the others, he shows that the dignity of each was the same. After he had established the proof of their unanimity, he takes courage, and proceeds confidently in his argument, not stopping at the Apostles, but advances to Christ Himself, and to the grace which He had conferred upon him, and calls the Apostles as his witnesses, saying,
Paul allows that Peter, following Jewish custom, was without blame in his temporary observation of what was amiss so as not to lose those entrusted to him. But it was Paul’s own duty for the sake of the gospel truth to do what was entrusted to him among the uncircumcised, so that the Gentiles would not depart from their faith and belief in Christ through fear of the burdens and rigor of the law.
